Why?

Why everybody is late at work?
Why nobody is really trying to make a change? (and they always say they will)
Why we are too lazy to reply to all the e-mails we get?
Why sometimes it's so easy to do one thing and impossible to do another and the next day is the other way around?
Why do we travel?
Why do we come back?
Why we are so tired during the week sleeping the same much as during the weekends?
Why do we have to go to work?
AAAA, that's why!
Why sometimes we have so many guests that we have to say no to some of them and sometimes nobody comes?
Why we have to write 10 e-mails looking for something and the answer we'll get from the first one?
Why do we meet people we don't need at the right time and people we really need at the wrong time? And sometimes people we don't need at the wrong time?
For this i have the answer: to meet people you need at the right time once every 10 years:))
